CYLINDER GP-RIPPER 3742277 - Caterpillar

(7) Torque for four nuts on the bearing caps ... 500 50 lb. ft.(680 70 N m)(8) Torque for ten bolts ... 75 5 lb. ft.(100 7 N m)(9) Torque for the studs (not shown) that hold bearing caps (11) and (15) to the differential carrier ... 320 30 lb. ft.(435 40 N m)(25) Torque for 14 nuts that hold bevel gear (24) to differential assembly (13) ... 265 10 lb. ft.(360 14 N m)(27) Torque for eight nuts that hold the housing of differential assembly (13) together ... 294 11 lb. ft.(400 15 N m)Adjustment Procedure For The Bevel Pinion Bearings:
1. Install bearings (3) and (14), and ring (10) on pinion (2).2. Install pinion (2) in carrier assembly (18).3. Use shims (1) as necessary behind cage (16) to put enough preload on the pinion bearings so the torque needed to turn the pinion (2) is more than ... 35 lb. in.(4.0 N m)4. Turn the pinion several revolutions. Change thickness of shims (1) so that a torque of 35 5 lb. in. (4.0 0.6 N m) is needed to make a rotation of the pinion. Turn pinion (2) slowly while adjustment is made. Do not install the seal (12) and "O" ring seal (17) in cage (16) until after the correct adjustment has been made. Then install "O" ring seal (17) with lubricant on seal in cage (16). Install seal (12) in cage (16) with lubricant on the lip of seal (12). The lip of seal (12) must be toward bearing (14).4. Hand tighten ten bolts (8) that fasten cage (16) to carrier assembly (18) to a torque of ... 75 10 lb. ft.(100 14 N m)Adjustment Procedure For Free Movement (Backlash) Between The Bevel Pinion And The Bevel Gear:
1. Install differential assembly (13) in carrier assembly (18) complete with bearing cups (6) and (21) and bearing cones (5) and (19). Install bearing caps and nuts (7). Do not tighten nuts (7) to full torque.2. Put carrier assembly (18) in position so that the teeth of bevel gear (24) are at the top, as shown, and the center line of the axles is vertical. 3. Use a dial indicator to measure the backslash between bevel gear (24) and pinion (2) at four different points on the bevel gear. Find the average backlash.4. Turn adjustment ring (26), until the average backlash between bevel gear (24) and pinion (2) is ... .014 .005 in.(0.36 0.13 mm)5. Tighten four nuts (7) on bearing caps to a torque of ... 500 50 lb. ft.(680 70 N m)Adjustment Procedure For Preload Of The Differential Bearing:
1. Install a dial indicator and turn adjustment ring (4) clockwise until dimension (A) has increased by ... .020 to .025 in.(0.51 to 0.64 mm) This will give the correct preload to the bearings.2. Turn the bevel gear in each direction
